Hi,

I just removed the supercharger from my 2003 R53. I was taking off the large plastic tube that connects to the back side of the blower and trying to disconnect the two breather lines. I was afraid I snapped the small grey breather tube:



Possibly snapped grey breather tube

After I got the supercharger fully off the car I think I might have just pulled it out of a rubber tube.

Grey tube fits in this rubber tube?
Is this where it fits?

Thanks,
Eric

 

Believe one of those goes to the brake booster, the other to the manifold air pressure sensor:

I think that hose is a patch job. I broke my MAP tube last year closer to the sensor and bought a whole new tube. It is one piece from the sensor to the supercharger inlet pipe.

But if that hose works, then it works.
